1 Equipment class designations consist of a combination (in sequential order separated by periods) of: (1) An equipment family (ESCC = end suction close-coupled, ESFM = end suction frame mounted/own bearing, IL = in-line, RSV = radially split, multi-stage, vertical, in-line diffuser casing, ST = submersible turbine; all as defined in § 431.462 ) ; (2) nominal speed of rotation (1800 = 1800 rpm, 3600 = 3600 rpm); and (3) an operating mode (CL = constant load, VL = variable load). Determination of the operating mode is determined using the test procedure in appendix A to this subpart.
2 For equipment classes ending in .CL, the relevant PEI is PEICL. For equipment classes ending in .VL, the relevant PEI is PEIVL.
3 The C-values shown in this table must be used in the equation for PERSTD when calculating PEICL or PEIVL, as described in section II.B of appendix A to this subpart.
Equipment class | Minimum allowable WEF score [kgal/kWh] | Minimum allowable WEF score [kgal/kWh] | |
Dedicated-purpose pool pump variety | hhp Applicability | Motor phase | |
Self-priming pool filter pumps | 0.711 hp [LESS THAN EQUAL TO]hhp [LESS THAN]2.5 hp | Single | WEF = -2.30 * ln (hhp) + 6.59. |
Self-priming pool filter pumps | hhp [LESS THAN]0.711 hp | Single | WEF = 5.55, for hhp [LESS THAN EQUAL TO]0.13 hp -1.30 * ln (hhp) + 2.90, for hhp [GREATER THAN]0.13 hp. |
Non-self-priming pool filter pumps | hhp [LESS THAN]2.5 hp | Any | WEF = 4.60, for hhp [LESS THAN EQUAL TO]0.13 hp -0.85 * ln (hhp) + 2.87, for hhp [GREATER THAN]0.13 hp. |
Pressure cleaner booster pumps | Any | Any | WEF = 0.42. |
